FRANK BIANCHI, OF WEST HOBOKEN, NEW JERSEY, ASSIGNOR TO THE SCHWARZEN- EACH HUBER 00., OLE WEST HOBOKEN, NEW JERSEY, A CORPORATION OF NEW JERSEY.

THREAD GUIDE.

Application filed June 2,

To all whom it may concern.

Be it known that I, F RANK' Binvoiri. a citizen of the United States, residing at West Hoboken, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Thread Guides, of which the following a. specification.

The invention relates to guides eu'iployed in winding or spooling operations, such as the transfer of filaments from the swifts to the bobbins. in a silk winding machine. and the object of the invention is to provide a guide of simple construction adapted to reccive interchangeably any one of a plurality of eyes, and permit the substitution of one for the other to be easily and quickly effected in accordance with the kind or quality of the filament to be cleaned and wound.

The invention consists in certain. novel features of construction and arrangement by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an appro er form of the invention.

Figure 1 is a front elevation showing two adjacent guides in place on the usual reciprocating bar of a winding machine.

The remaining figures are on a larger scale and show the guide and eyes alone.

Figure 2 is a front view of one of the guides.

Figure 3 is a plan view of the same.

Figure 4 is acorresponding end view.

Figure 5 is a vertical transverse section taken on the line 5-5 in Figure 2.

Figure 6 is a vertical longitudinal section taken on the line 6-6 in Figure 4;.

Figures 7, 9 and 11 are face views of eyes adapted to serve with the guides shown in the preceding figures.

Figures 8, 10 and 12 are corresponding plan views of the same.

Similar reference naunerals indicate the same parts in all the figures.

The reciprocating bar on which the guides ing a wide base in which is a longitudinally 1923. Serial No. 642,995.

extending V-shaped channel 18 adapted to apply upon the correspondingly shaped edge of the bar 15, and a narrower top in which is a longitudinal groove 19 adapted to receive the ends of the spring fingers 16 by which the guides are held yieldingly in place to permit adjustment on the bar.

Angularly disposed swells 20 on the outer face of the block provide a shallow tapering way 21 between them serving to lead the filament, not shown, from a swift below, or a bobbin or any thread package, not shown, to a deep score or narrow notch 22 extending transversely of the guide at about the centre of the top, and thus through the guide to the bobbin, not shown.

In the central portion of the guide, extending downwardly from the groove 19, is a deep cavity or recess 23 into which the notch 22 extends. This recess is shaped to receive loosely and retain by gravity a tablet or eye laid vertically therein which may be of any of the forms shown in Figures 7 9 and 11 or other form. I11 Figures 2 to 6 inclusive the eye 24, shown in Figures 7 and 8, is shown in dotted lines mounted in the recess 23.

The eye 24 is of steel having a very 'fine vertical slit 25 therein which coincides with the notch 22; the filament passes through the slit in its traverse across the guide.

The eye 26 shown in Figures 9 and 10 comprises a wire folded upon itself in M- shape and is carried in the recess 23 in the same manner as before, with its central slit 27 receiving and guiding the filament.

The eye 28 shown in Figures 11 and 12 is formed of a series of fiat wires standing parallel with each other and mounted in a base, and is similarly inserted in the recess 23 with the filament passing between any pair of adjacent wires registering with the notch 22. a

The various forms are used in adapting the guides for service with various kinds of materials and various types of machines. The eyes serve in cleaning the filaments by removing particles and shreds adhering thereto, and in equipping the respective ma chines for either kind of filament it is only necessary to supply the series of guides with the proper kind of eyes.

Modifications may be made in the forms and proportions as found i'iecessary or de sirable in adapting the invention to various types of Winding machines, and the improved guides may be employed in other situations bar, said body having a recess in such (op 10 to which they maybe adapted. and a'transverse HOlSCh'GZIlQJNllDP; into such Iclaimzrecess, and an eye loosely and removahly The guide described comprising a body mounted in such recess and having a slit lo having a. longitudinally extended channel in cated to register- With such notch.
